Definitions

  • the second product collected by the second product collector 27 is transported diagonally upward and frontward by the second product returner 32, and is returned to the upper side (upstream side of the sorting unit 42) relative to the swinging sorting apparatus 24.
  • the second product returner 32 is constituted by a screw-type conveyor.
  • the sieve case 33 includes a first grain pan 34, a plurality of first sieve lines 35, a second sieve line 36, a second grain pan 37, a first chaff sieve 38, a second chaff sieve 39, a grain sieve 40, an upper grain pan 61, and a lower grain pan 65.
  • the processed product that has leaked through the front end side portion of the first chaff sieve 38 is partially removed by sending part of it to the rear side using the sorting air immediately after leaking, and the processed product including a large amount of grain is received by the upper surface of the grain sieve 40. Furthermore, since the air pressure of the sorting air and the swinging force act on the processed product supplied to the grain sieve 40, the straw and the like included in the processed product are sent toward the rear on the upper surface of the grain sieve 40, and the processed product that leaks through the grain sieve 40 includes a large amount of grain.
  • the grain that has leaked through the grain sieve 40 flows down from the first product guide 62 to the first product collector 26 and is collected, and is stored in the grain tank 12 by the first product collection transporter 29.
  • the swinging sorting apparatus 24 sorts the grain as the sorted product from the processed product, but the amount of the sorted product to be sorted can be changed in accordance with the return amount detected by the return amount detector 71.
  • the amount of the sorted product to be sorted being changeable in accordance with the return amount means that the sorting ability of the swinging sorting apparatus 24 can be changed in accordance with the return amount.
  • the sorting ability of the swinging sorting apparatus 24 corresponds to the ratio of the amount of the first product collected by the first product collector 26 to the amount of the processed product leaking from the receiving net 23, that is, the degree of sorting (or the sorting efficiency).
  • the support base end portion region of the guide 32C is formed into a circular arc shape, and the guide 32C is formed so as to be closer to a linear shape toward the leading end side (the side away from the side wall 50).
  • the swing arm 72 and the guide 32C approach each other in a state in which the swing arm 72 is positionally held in the downward standby orientation.
  • the separation distance between the swing arm 72 and the guide 32C is the same over the region from the swing base end portion where the rotation shaft 76 is located to the free end portion located below the rotation shaft 76 of the swing arm 72.
  • the pressure-receiving portion 101 is connected to the pressure-sensitive portion 100 via the supporting portion 102 such that the pressure-sensitive portion 100 can detect the pressure from the second product guided by the guide 32C.
  • a through hole 104 is provided that penetrates in a direction orthogonal to both the direction of a line connecting the two end portions and the stacking direction of the pressure-sensitive portion 100 and the pressure-receiving portion 101. Accordingly, the return amount detector 71 can detect the return amount of the second product.
  • an operating arm 113 is provided on the rotation axis of the measurement portion 73, and the operating arm 113 extends outward in the radial direction.
  • a circular hole is formed in one of the operating arm 112 and the operating arm 113, and an elongated hole is formed in the other of the operating arm 112 and the operating arm 113.
  • the elongated hole extends along the other longitudinal direction.
  • the operating arm 112 and the operating arm 113 are coupled by a pin by inserting one pin 114 through the one circular hole and the other elongated hole.
